Description
Anatomical changes in the placement of the mandibular foramen (MF) can contribute to the inferior alveolar nerve (IAN) block's lower success rate compared to the maxillary nerve block. Before planning and conducting different endodontic operations, mandibular ramus surgeries, and other surgical treatments of mandibular fractures, dentofacial abnormalities, and tumours, the location of MF must be known. In addition to individual variation, there are significant ethnic and racial differences in the location of MF. Due to the paucity of osteological research in this area, the purpose of this study was to establish the position of the MF in Iraqi populations. This retrospective record review utilised cone beam computed tomography (CBCT) scans of respondents from the Arabic and Kurdish communities of Iraq. This research comprised 400 cases, including 200 Arabs and 200 Kurds, with 100 male and 100 female cases from each group using the RadiAnt DICOM viewer software. The appropriate measurements were viewed and taken. The visibility ratings and dimensions measurements were completed by a single researcher using intra-examiner calibration and inter-examiner calibration. The shape, size, and location of the MF were evaluated for each community and between the Arabic and Kurdish populations. The records were imported to the SPSS programme and statistically analysed (independent T-test for the measurements of the size and location of MF and chi-square test for the shape of MF) in order to compare the data between the different sexes, Arabs, and Kurds. This study revealed that 77.9% of lingula in the Arabic population were located above the occlusal table, whereas 22.1% were located below the occlusal table. In contrast, 87.9% of lingula in the Kurdish population were found to be above the occlusal table, 4.6% were within the occlusal table, and 2.8% were below the occlusal table. The shape and size of MF was seen to vary significantly. The findings of this study may provide new information on the size, shape, and position of the mandibular foramen in the Arabic and Kurdish people of Iraq. Important morphometric information for performing IAN blocks correctly and avoiding difficulties during mandibular surgery would also be provided by this study's findings.
